I've just bought a new monitor, connected everything but the screen keeps jumping and flickering. I followed the instructions in the troubleshooting manual which told me to adjust the Focus and Clock - I have the focus on 100 but it doesn't seem to help (it is horizontal lines that are making the screen flicker). I also followed the suggestions for reducing the screen resolution and reducing the colour settings, but if anything it's worse. Also, it came with an instruction to set resolution to 1280 x 1024 and I have done this. Help!
